Biography
William de Lamberton was born in Berwickshire, Scotland, and he became a canon of Glasgow and then chancellor of Glasgow Cathedral in 1293. In 1298, Pope Boniface VIII appointed Lamberton Bishop of St. Andrews, and Lamberton's appointment was supported by William Wallace due to his support for the patriotic cause during the Wars of Scottish Independence. Lambert took a young James Douglas as his squire after Douglas' father William became a leader of the Scottish rebels, and Lamberton befriended the young James and (unsuccessfully) attempted to convince King Edward I of England to restore the confiscated Douglas lands to James in 1304. During the wars with the English, William financed the Scottish rebels and served as a diplomat to France, and he was briefly excommunicated for his support for the Scots. He later came to support Robert Bruce, and, in 1306, he pardoned Bruce for his murder of John Comyn in a church, even going on to crown him King of Scotland. Lamberton was later forced to swear fealty to King Edward II of England, but he later helped to reconcile Scotland with the papacy. He died in 1328.
